Abstract

The invention discloses a suturing-free blood vessel graft and a supporting sleeve ring, relates to the technical field of medical instruments and aims to solve the technical problem that existing suturing-free sleeve rings are prone to causing operation difficulty (high diameter selectivity) or blood leaking (low diameter selectivity) due to fixed diameter. The suturing-free blood vessel graft comprises an artificial blood vessel body, a suturing-free connecting portion is arranged on the artificial blood vessel body and composed of a coating member and the supporting sleeve ring, the coating member is positioned on the outer side of the artificial blood vessel body and coaxially and seamlessly connected with the same, and the supporting sleeve ring is put between the coating member and the artificial blood vessel body; an adjusting portion is arranged on the supporting sleeve ring, part of the adjusting portion is exposed out of the coating member, and the adjusting portion is used for adjusting and fixing diameter of the supporting sleeve ring to enable the suturing-free connecting portion of the suturing-free blood vessel graft to be adjustable in diameter.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a suture-free vascular graft and a support ring. Background technique [0002] For a long time, some scholars hope to use a faster way to complete the anastomosis of the artificial vascular graft and the patient's own blood vessels, and have made many attempts. Mechanical vascular anastomosis technology is a vascular anastomosis method that replaces or partially replaces sutures with a special vascular anastomosis device, which can overcome the defects of traditional vascular anastomosis methods such as complicated operation, long anastomosis time and serious intimal damage. At present, the commonly used mechanical vascular anastomosis techniques in experimental research and clinical application mainly include magnetic tube method, cannula method, needle ring method and anastomotic clip method. [0003] In the middle of the twentieth century, Ablaza and Dureau reported t...
